1 Claim.

My invention relates to door stops or checks, and more particularly to a device for this purpose which may be secured in place without the necessity of any fastening elements and without marring the surface upon which it is secured.

It often occurs that there is a necessity of having a door check or stop in a certain position, but the ordinary devices made for this purpose would require the use of fastening elements and would, to some extent, mar the surface to which they are secured. It is also true that very often one has need of a door stop which may be readily moved from one position to another, or placed in a certain position temporarily, and in such case it is, of course, desirable that the stop be readily secured in place and detached, and at the same time that these operations may be performed without leaving any marks such as screw holes or the like. In addition, it is often desirable to employ a door check Which may be secured upon the floor to hold the door in any predetermined open position, and it is of great advantage to have a stop of such character that it may be readily secured in place and detached when its use is not desired.

One object of the invention is the provision of a device which may be employed either as a door check or door stop, or may be used in other similar situations, and which at the same time may be readily attached and detached to the wall or floor or other element which supports it.

A still further object of the invention is the provision of a door stop or check which may be readily secured in place without the employment of any fastening elements, such as nails, screws,

or the like.

A still further object of the invention is the provision of a door check or stop made entirely of rubber, which may be secured in place by means of a vacuum cup formed integrally with the body of the device, whereby the device may be readily secured in place without marring the supporting surface, and at the same time a very efficient check or stop is provided at a minimum cost.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the drawing:

Fig. 1 is an elevational view of a portion of a door showing my device employed as a door check;

Fig. 2 is a plan view of a door showing my 55 device employed as a door stop;

Fig. 3 is a side elevational view of the door check or stop;

Fig. 4 is a top plan View of the same; and

Fig. 5 is a sectional view of the device when secured in place upon a supporting surface. 5

In order to illustrate one preferred embodiment of my device, I have shown a door check or stop which will preferably be made entirely of rubber, so that it will serve to check the door or hold it in a predetermined open position with- 10 out marring the door itself. Also, as will be hereinafter described, when the device is made entirely of rubber the lower skirt portion or vacuum cup may be formed integrally with the remainder of the device, so that economy in manu- 15 facture will result.

The device comprises a body portion or post In which, as shown in Fig. 5, may be of solid rubber, so that it will be relatively firm and stiff and have sufificient rigidity to perform the required 20 function. At the lower end of the body portion is provided a flexible rubber cup I I which serves as a vacuum cup in the operation of the device. At the lower end of the post I0 is provided a relief recess I2 which communicates with the 25 interior of the vacuum cup II. As shown in Fig. 5, the skirt portion or wall of the vacuum cup I I may taper in thickness toward the free edge Il so that this skirt portion is considerably thinner and more flexible at its free edge than adjacent 30 the post or body portion I0.

It will be understood that when it is desired to secure the device in place, the lower open end of the vacuum cup or skirt portion is pressed firmly against a flat surface, such as the wall or 35 floor. It is preferable to moisten the perimeter of the skirt portion so as to secure a better vacuum. When the skirt is pressed against the flat surface, it will flatten out, as shown in Fig. 5, the air being expelled from beneath the skirt so 40 as to create a partial vacuum therebeneath. When the device is released the air pressure on the upper side of the skirt will, as in a wellknown manner, hold the device securely in position. 45

It will be seen that the stop or check can be readily secured in any desired position without the use of any fastening elements and without marring the surface by which it is supported, and that, as the stop itself is made of rubber, it will 50 not mar the door or other device with which it is intended to contact.

In Fig. 1 of the drawing I have shown my device employed as a door check. In this case the check, indicated generally by the numeral I3,

is supported from the surface of the floor I 4 in such position that it will be engaged by the door l5 so as to hold the door in a desired open position, as shown in this figure. It will be apparent that the check may be secured in any desired position upon the floor so as to hold the door open at the desired angle, and, when it is desired to close the door, the check may be readily taken up. In Fig. 2 of the drawing the device, designated generally by the numeral I3, is shown secured to the wall IS in a horizontal position so that it will serve as a door stop by engagement with the side of the door I! when the latter is opened. The device may be readily secured in any desired position upon the wall so as to contact with the door at any desired height, or at any desired point in the width of the door, and it may, of course, be secured to a plastered wall as well as to th wooden base board.

Although the body portion ill of the device is described as relatively firm and stiff, this does not mean that it is made out of hard rubber, as that term is usually employed, for this portion of the device will usually be made of soft rubber and of the same material as the skirt portion I I. Ow-

ing to the fact that it is solid and relatively thick, it will, of course, be relatively rigid as compared to the skirt portion, so that it will effectively serve as a stop or check, but at the same time be sufficiently soft so that it will not mar the door in connection with which it is used.

While I have shown and described a preferred embodiment of my invention, it will be understood that it is not to be limited to all of the details shown but is susceptible of modification and variation within the spirit of the invention and within the scope of the appended claim.

What I claim is:

An all-rubber door check or stop comprising a relatively rigid post portion and a cup-shaped flexible skirt portion formed integrally therewith, said post portion being relatively long as compared with its cross-sectional dimension and being of constant cross-sectional area substantially throughout its length, and the wall of said skirt portion tapering in thickness from its connection with the post to its outer edge, and said post portion having a recess at its lower end opening into the cup of said skirt portion.
